The touchscreen technology worked, but not as perfectly as it did in the demo, at least in my brief experiment with the prototype. In particular, I had real problems with the software keyboard: My thumb-typing was consistently hitting keys adjacent to the ones I targeted. The iPhone has auto-correcting text entry technology that's supposed to figure out what word you were trying to enter, but there's a limit to its second-guessing skills after you've entered three or four incorrect characters in a row. Joswiak kept telling me to stop trying to backtrack and correct the typos ("Have faith," he said repeatedly), but it just wasn't working for me.
